Try out Google Docs

Google Docs (now known as Google Drive) is a free, Web-based office suite and data storage service offered by Google. It allows users to create and edit documents online while collaborating in real-time with other users. Google Docs combines the features of Writely and Spreadsheets with a presentation program incorporating technology designed by Tonic Systems. Data storage of files up to 1 GB total in size was introduced on January 13, 2010, but has since been increased to 10 GB, documents using Google Docs native formats do not count towards this quota.[3] The largely anticipated cloud storage feature by Google is said to be replacing most of Docs’ features in 2012.[4] This extension or replacement of Google Docs called Google Drive was opened to the public on April 24, 2012.
